A double-stranded DNA rotaxane.
Mechanically interlocked molecules such as rotaxanes and catenanes have potential as components of molecular machinery. Rotaxanes consist of a dumb-bell-shaped molecule encircled by a macrocycle that can move unhindered along the axle, trapped by bulky stoppers. Previously, rotaxanes have been made from a variety of molecules, but not from DNA. Here, we report the design, assembly and character...
متن کاملThe conformation of double-stranded DNA inside bacteriophages depends on capsid size and shape.
The packaging of double-stranded DNA into bacteriophages leads to the arrangement of the genetic material into highly-packed and ordered structures. Although modern experimental techniques reveal the most probable location of DNA inside viral capsids, the individual conformations of DNA are yet to be determined. In the current study we present the results of molecular dynamics simulations of th...
متن کاملMolecular Effects of Atmospheric Pressure Plasma Jet on the Double-Stranded DNA
Introduction The aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (APPJ) and interactions of this technology with double-stranded DNA using the polymerase chain reaction (PCR) and single-strand conformation polymorphism (SSCP) techniques. Materials and Methods The plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...
متن کاملIntroducing a New and Simple Protocol for Capillary Electrophoresis of Cell Free Fetal Double Stranded DNA
Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we propos...
متن کاملNonlinear waves in double-stranded DNA.
We propose a nonlinear model derived from first principles, to describe bubble dynamics of DNA. Our model equations include a term derived from the dissipative effect of intermolecular vibrational modes. Such modes are excited by the propagating bubble, and we term this 'curvature dissipation'. The equations that we derive allow for stable pinned localized kinks which form the bubble. We perfor...
